For a dinner that uses several tins, start by checking how much tuna the pack provides after draining: the net weight also includes packing liquid. Choose the liquid and chunk or steak format to suit the recipe, and consider a no-drain pack when avoiding the draining step matters more than buying a conventional multipack.
If pasta bakes, jacket potatoes or salads use several tins at once, check the pack’s drained weight before deciding how many tins a recipe needs. Tesco Groceries lists 4 x 102g drained tuna in its 4 x 145g spring-water pack.
A multipack can keep several tins in the cupboard, but tin count and net weight do not tell you the full drained amount. Check the label when choosing between four-tin, six-tin and larger bundles.
John West offers a no-drain spring-water format for meals where you would rather skip conventional draining. If certified sourcing matters to you, look for the MSC ecolabel on the exact pack rather than assuming it applies to every product from a brand.
Work out the drained amount your dinner calls for, then narrow the choice by packing liquid, preparation and the information on the exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Usable amount | Read the drained weight as well as the net weight and tin count. Tesco Groceries states 4 x 102g drained for one 4 x 145g spring-water pack. | I need enough tuna after draining for the portions I plan to make, not just a large-looking pack. |
| Pack format | Check the number and size of tins, and whether the format is chunks or steak. For a large bundle, confirm the quantity on the exact product listing. | If I cook with tuna often, several smaller tins may be easier to open across separate meals; a larger tin may suit a recipe using more at once. |
| Packing liquid | Compare the exact ingredients and nutrition panels for spring water, brine or oil. Tesco Groceries lists 0.90g salt per 100g drained for its cited spring-water pack and 1.00g for its cited brine pack. | I want the liquid and seasoning to fit this meal, without assuming every product packed in brine or spring water has the same salt figure. |
| Preparation | Check whether the particular pack is labelled no-drain. John West identifies a no-drain spring-water product; that feature should not be assumed for its other tuna packs. | On evenings when I want fewer preparation steps, I may prefer a pack I can use without conventional draining. |
| Sourcing | Look for an MSC ecolabel or a specific traceability statement on the product you are considering. Check its drained weight and ingredients separately. | I want a product-level sourcing label I can recognise while still choosing a format that works for dinner. |
| Handling | Read the fish-allergen and possible-bones information, along with the opened-tin storage instructions on the label. | If a tin will not be used in one meal, I need a plan for storing the remainder as its label directs. |
A 4 x 145g net-weight pack does not necessarily provide 580g of drained tuna. Tesco Groceries states 4 x 102g drained for its spring-water four-pack.
Use the stated drained weight to estimate how many tins your recipe calls for.
Salt figures can differ even between similar-looking packs. Tesco Groceries lists 0.90g salt per 100g drained for its cited spring-water tuna and 1.00g for its cited brine version.
Read the ingredients and nutrition panel of the exact product, especially when switching liquids or brands.
Unused tuna needs handling according to its pack instructions. Asda Groceries directs shoppers to transfer opened-tin leftovers to a suitable non-metallic container, cover and refrigerate them, and use them within two days.
Check storage directions before opening several tins, and plan another use for any leftovers.

Choose the liquid that fits your recipe, then read the exact pack’s ingredients and nutrition panel. In the cited Tesco Groceries packs, the spring-water version lists 0.90g salt per 100g drained and the brine version lists 1.00g; those figures should not be assumed for other products.
Follow the instructions on your pack. Asda Groceries directs shoppers to transfer unused tuna to a suitable non-metallic container, cover and refrigerate it, and use it within two days.
Tuna is fish, so check the fish-allergen declaration on the exact product. Also read any possible-bones warning and inspect the tuna as you prepare the meal, particularly when serving children.
No. An MSC ecolabel identifies a sourcing certification on the labelled product; it does not tell you its drained weight, packing liquid or nutrition. Check those details separately when choosing tuna for dinner.
